ruby-mp3info

I have an old SanDisk mp3 player that I use to listen to music and podcasts. Though it's a rather small card (512M), it's still annoying to have to scroll through my single playlist to get to a specific file.

The SanDisk sorts by the mp3 info title tag, so I wrote a small script that I run on my podcast files before I load them on my player so that they will show up first in the playlist by prepending '01_' to the mp3 title tag (and using the mp3 filename if the title is nil).

First, install the ruby-mp3info gem if you don't have it:

gem install ruby-mp3info

edit_mp3info_title.rb

require 'rubygems'
require "mp3info"

dir = Dir.open('/Users/dsparlingimbp/PODCAST/mp3')
puts "mp3 directory: #{dir.path}"

dir.each do |file|
  next unless /\.mp3$/ =~ file
  puts "mp3: #{file}"

  mp3file = "#{dir.path}/#{file}"

  Mp3Info.open(mp3file) do |mp3|
    puts "original title: #{mp3.tag.title}"
    title = '01_' + (mp3.tag.title || file)
    mp3.tag.title = title
    puts "new title: #{mp3.tag.title}"
  end

end
